Question

The app that I am developing is messing with me. I have three activities at the moment (all of which are defined in the manifest), that all transition into eachother i.e intro–>activity1–>activity2. The transition from the intro to the first activity works fine using:

public void GOTOGPS(View v)
{
    switch (v.getId()){

    case R.id.button1: startActivity(new Intent(v.getContext(), StreetLightOutageActivity.class));//Jump to StreetLightOutageActivity (main.xml)
    default: break;

    }//switch
}//GOTOGPS

However, the method in my second activity “StreetLightOutageActivity” that is used to go to my third activity does not work:

 public void GOTOCAMERA1(View v)
{

    switch (v.getId()){

    case R.id.picturebutton: startActivity(new Intent(v.getContext(), Camera.class));
    default: break;

    }//switch

}//GOTOCAMERA1

LogCat gives me an ActivityNotFoundException:

05-17 15:51:41.292: E/AndroidRuntime(534): Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {sl.reporter/android.hardware.Camera}; have you declared this activity in your AndroidManifest.xml?

and then an InvocationTargetException which I assume stems from the previous exception:

05-17 15:51:41.292: E/AndroidRuntime(534): Caused by: java.lang.reflect.InvocationTargetException

Now what is really getting me, is that if I modify the method to transition from my introscreen to my second activity to go to “Camera.class” instead of StreetLightOutageActivity.class, It works.

finally, here is my manifest just in case it helps,

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="sl.reporter"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

<application
    android:icon="@drawable/ic_launcher">
     <activity
         android:name=".StreetLightOutageActivity">
     </activity>
     <activity
        android:name=".Camera">
     </activity>
     <activity
        android:name=".Introscreen">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
     </activity>
</application>

Answer 1

case R.id.picturebutton: startActivity(new Intent(v.getContext(), Camera.class));

I think in the above code you want to use sl.reporter.Camera class, but mistakenly you end up using android.hardware.Camera.
